A homeless man who gave his last $20 to ensure a motorist got home safe has had his kindness repaid thousands of times over thanks to a GoFundme page set up in his honour.

So far the campaign has raised over $75, 000 USD ($109,122 NZD) in 12 days, despite only being set up with a $10,000 ($14,549 NZD) goal.

The page was started by American woman Kate McClure, 27, who was driving into Philadelphia last month to visit a friend when her car ran out of petrol.

According to the account she posted on GoFundme, a homeless man approached her saying she should to lock her doors and stay in the car. He then left and returned with a can of petrol - reportedly using the last of his money to buy it.

The Philadelphia Inquirer reports the homeless man is Johnny Bobbitt Jnr, 34, a marine corps veteran who fell on hard times after running into money and drug problems.

As well as setting up the crowd funding page for him, Ms McClure has frequently returned to visit Mr Bobbitt Jnr with gifts of food and clothing.
